New to LS4's Been lurking for a while... as my user ID would imply, I am a fiero guy and have done numerious engine swaps into fieros (SBCs, 4.3, 4.9, 3.4...).
I recently aquired a 2007 Impala SS LS4 engine/tranny, but it will be a while before I start tearing into the LS4 for cam/headers/intake upgrades and mounting it to the F40 6 speed manual.

Thanks for the Welcomes!
I have been researching the Fiero/LS4 swaps for quite some time and I think there are 5 of 6 completed swaps so far with the assistance of GMTuners.com, westcoastfieros.com and fieroaddiction.com supplying some of the swap parts and ecm tuning.
Completed Fiero LS4 Swaps:

LS4 Fiero Swaps underway:

Most of the completed swaps were installed in near stock form with the the 4T65e-HD and factory exhaust manifolds. I want to perform some upgrades (375+ whp), run a manual transmission (already past that hurdle), and build a set of headers for mine. The other challange will be to keep DoD operational with the manual transmission. From researching the 07 Impala FSM, there are only 3 tranny related functions that inhibit DoD engagement. Still unsure if I would be better off keeping the TCM and spoofing it, or if I can do it diretly to the ECM... back to do more research...
